Entrepreneurial orientation (EO) has long been treated as a straightforward path to innovation. Firms that take risks, act proactively, and pursue novel ideas are expected to outperform those that maintain conservative strategies. Yet the evidence has never been fully conclusive. A new study challenges the assumption that "more EO is always better," demonstrating instead that EO affects innovation performance in a U-shaped pattern. Both low-EO firms - those that innovate incrementally - and high-EO firms - those that innovate aggressively - tend to outperform firms in the middle, whose ambidextrous position imposes greater internal strain.
Published in Industrial and Corporate Change, the study draws on a large dataset from the 2020 Korean Innovation Survey, which provides rare, concurrently measured information on firms' entrepreneurial orientation and innovation outcomes. The authors combine theory from entrepreneurship, organizational learning, and the attention-based view (ABV) of the firm to explain why certain firms - despite being more entrepreneurial - may not extract meaningful innovation benefits from their internal posture.
Entrepreneurial orientation comprises five traits: risk-taking, proactiveness, innovativeness, competitive aggressiveness, and autonomy. These dimensions collectively determine a firm's strategic posture toward uncertainty and opportunity. Firms high in EO tend to pursue radical innovation, experiment with new markets, and aggressively respond to competitors. Firms low in EO tend to optimize existing processes, enhance efficiency, and improve current products through incremental changes. Both approaches can succeed - but not equally and not at all stages.
The researchers argue that innovation performance depends on the net benefit of EO after subtracting the costs required to support it. High EO offers the potential for major innovation breakthroughs, but it requires substantial managerial attention, cultural alignment, and strategic reconfiguration. Low EO offers modest innovation gains at lower cost. The result is a U-shaped curve: firms at both ends see stronger innovation performance, while firms around the midpoint struggle. These mid-level firms must balance exploration and exploitation simultaneously, stretching managerial attention across incompatible demands, and often failing to gain the advantages of either approach.
The study then introduces a second crucial factor: external knowledge search. Firms can complement internal EO by looking outward - building partnerships, sourcing ideas, and integrating external expertise. The authors distinguish between two types of external search. Breadth refers to drawing information from many different types of partners, while depth refers to engaging intensively with a small set of highly relevant partners.
Using ABV as the theoretical lens, the researchers argue that breadth and depth impose different attentional demands. Breadth requires attentional breadth - the ability to monitor and integrate diverse inputs. Depth requires attentional intensity - the ability to focus deeply and consistently on selected partners. These cognitive and managerial constraints, in turn, shape whether EO translates into successful innovation or costly misalignment.
Empirically, the analysis finds that broad external knowledge search weakens the U-shaped relationship between EO and innovation performance. Breadth increases the marginal costs of EO because firms must allocate additional attention to sourcing, evaluating, and integrating knowledge from many external channels. This overload is particularly challenging for intermediate-EO firms, which already face tension from balancing incremental and radical innovation. As breadth increases, the distinctive advantage of low-EO and high-EO firms narrows, while intermediate firms still struggle with coordination demands.
Depth, by contrast, strengthens the U-shaped relationship. Deep partnerships help firms translate high EO into impactful innovation by channeling attention into focused learning and committed collaboration. For conservative firms, deep partnerships supplement internal learning deficits and help avoid competence traps. For entrepreneurial firms, depth supports the assimilation of complex, high-novelty knowledge needed for radical innovation. Thus, depth amplifies the advantages at both ends of the EO spectrum while widening the gap for firms in the middle.
The Korean manufacturing context provides an interesting backdrop for interpreting these results. Many Korean small and medium-sized enterprises (SMEs) operate with limited managerial attention, limited absorptive capacity, and verticalized industrial structures. These constraints create a natural setting where U-shaped EO effects are more visible. High-EO SMEs push aggressively into new technologies with clear innovation gains. Low-EO firms focus on incremental upgrades and process refinements, also generating positive outcomes. But firms attempting to straddle both - without the resources to support ambidexterity - may find themselves overwhelmed.
The study's results remain robust across multiple models, including Tobit regressions, instrumental-variable estimation to address endogeneity, and Heckman models accounting for self-selection into innovation. Across these checks, the central patterns persist: EO's effect on innovation is curvilinear, breadth weakens the U-shape, and depth strengthens it.
From the perspective of Seven Reflections' Dimensional Systems Architecture (DSA), these findings map naturally onto the logic of field saturation and attentional allocation. In DSA terms, EO represents an internal field configuration that shapes how a firm processes uncertainty and opportunity. Intermediate EO corresponds to a cognitively unstable configuration - one in which the system attempts to operate across multiple field trajectories simultaneously, generating friction and inefficiency. High or low EO represent stable poles, allowing the system to concentrate its cognitive bandwidth either on exploitation or exploration.
External knowledge search acts as an external field input. Breadth expands the system's external field without increasing coherence, leading to fragmented attention and weakened performance - an echo of high-entropy states in DSA logic. Depth, however, creates a coherent coupling between internal EO and external knowledge, strengthening resonance across fields. In this view, innovation performance emerges not only from strategic choices but from the structural interplay between internal orientation and the informational environment. Firms succeed when these fields align in a stable configuration.
The study demonstrates that innovation is not simply a matter of being more entrepreneurial. Instead, firms must understand how their strategic posture interacts with external search practices under the constraints of managerial attention. Conservative firms may benefit from deep partnerships that compensate for limited exploratory capacity. Entrepreneurial firms may amplify their strengths by cultivating focused external collaborations rather than spreading attention too broadly. Firms caught in the middle must either stabilize around a clearer posture or reconfigure their resource systems before expanding external search.
These findings offer practical guidance for managers: EO is powerful, but only when aligned with the right external search strategy. Innovation thrives not on maximal intensity but on structural coherence between what a firm is internally and how it absorbs information from the outside.
